Sbox-Claude

Use when building, modifying, or polishing any feature in an s&box game project through the Claude Bridge — gameplay systems, UI panels, character abilities, animation, world generation, anything that produces a visible or runtime change. Codifies the screenshot-driven iteration workflow that prevents the "guess-and-check" loop the bridge is most susceptible to.

Use when writing or modifying code for s&box, sbox, the Facepunch sandbox engine, or any Source 2 game project in C#. Triggers on mentions of s&box, sbox, sandbox game, Facepunch engine, Source 2 game, `.sbproj`, `.razor` with `PanelComponent`, `@inherits PanelComponent`, `Sandbox.Component`, `GameObject` + `Components.Get<T>`, `Scene.Trace`, `CharacterController` + `.Move()`, `SkinnedModelRenderer`, `NavMeshAgent`, `[Sync]`, `[Rpc.Broadcast]`, `[Property]`, `INetworkListener`, `ISceneEvent`, `PlayerController` in C#. Also triggers on any file with `using Sandbox;` or `using Sandbox.UI;` that isn't Unity/Godot/Unreal. Writes idiomatic s&box C# components, Razor UI, and networking code; prevents Unity-pattern leakage.

Use when building a whole s&box game or a specific game SYSTEM and you want a proven, code-grounded recipe instead of guessing. Genre playbooks (tycoon/idle, shopkeeper/management, deathmatch/arena, platformer/obstacle course, survival/horror, card-battler, gacha/dungeon-crawler, social-hub, document/inspection sim, puzzle, sandbox/voxel, vehicles, roleplay) and per-system how-tos (inventory, economy/currency, shop/vendor/trading, save/persistence, progression/upgrades/prestige, gacha/loot tables, leaderboards/services, idle/offline earnings, building/placement, crafting, dialogue, round/match flow, spawning/waves, anti-cheat) plus engine references (networking & authority, architecture, player controller, Razor UI, weapons/combat, input, physics/traces, component lifecycle, worldgen/rendering, performance/threading, data assets). Triggers on "how do I build a <genre> game", "inventory system", "save system", "economy / currency", "shop", "upgrade / prestige tree", "leaderboard", "round system", "spawn waves"

Use when the user asks for a whole playable game in one go through the s&box Claude Bridge — "make me a first-person game", "scaffold a game", "give me something I can press Play on". Orchestrates the existing bridge tools plus the gameplay scaffolds (objective/health/pickup/interactable/loot-table/save-system + wallet/phase-machine/day-night-clock + round-state-machine/interaction-station/event-director/save-slots + set_component_reference + add_component_to_new_object) into a first-person starter you can enter play mode in and move around, see a level, and win or lose. Handles the generate→hotload→place sequencing and the screenshot verify loop.

First-run onboarding for the s&box Claude Bridge. Run when a user first connects the bridge or asks how to get started — it verifies the connection, detects their installed libraries, recommends what to build with, and points them to help + feedback. Keep it warm and brief.
